Receiver Range

IR Receiver Location

To ensure proper function of the remote control follow the steps below:

1. The remote control must be held at an angle within 30° perpendicular to the projector’s IR remote control sensor(s).
2. The distance between the remote control and the sensor(s) should not exceed 8 m (26 ft.).
Note: Refer to the illustration for the location of the infrared (IR) remote control sensor(s).

Replacing the Batteries

With this mode, you can shadow detail when playing games. User User’s custom settings. 3D Is suitable for 3D content. NOTE: 3D glasses are needed.
	Brightness The higher the value, the brighter the image. Lower values will result in a darker image.
	Contrast The higher the value, the greater the contrast. Use this to set the peak white level after you have previously adjusted the Brightness setting to suit your selected input and viewing environment.
	Sharpness A high value results in a sharper picture; a low value softens the picture.
	Color Adjusts an image from black and white to fully saturated color.
	Tint The higher the value, the more greenish the picture becomes. The lower the value, the more reddish the picture becomes.
	Gamma Reflects the relationship between input source and picture brightness.
	Color Settings Setting Description Brilliant Color™ A color-processing algorithm and enhancements to enable higher brightness while providing true, more vibrant colors in picture. Color Temperature Select from Warm, Standard, Cool, or Cold. Color Management Only in permanent installations with controlled lighting levels such as: boardrooms, lecture halls, or home theaters should Color Management be considered. Color Management provides fine color control adjustment to allow for more accurate color reproduction, should you require it. If you have purchased a test disc, which contains various color test patterns and can be used to test the color presentation on monitors, TVs, projectors, etc., you can project any image from the disc on the screen and enter the Color Management menu to make adjustments. Color Space Select from Auto, RGB (0~255), RGB (16~235), and YUV color space.
	Light Source Mode Mode Description Dynamic Black Automatically adjusts the picture brightness in order to give optimum contrast performance. Eco. Automatically dims the light output, lowering power consumption. Power Select the power percentage (50%~100%) for brightness.
	Reset Returns current display mode settings (Brightness, Contrast, Sharpness, Color, Tint, Gamma, Brilliant Color, Color Temperature, Color Management, Color Space, Light Source Mode) to default.
3D	3D Mode Enables or disables the 3D function.
	3D Format Select the 3D content format. NOTE: A Blu-ray 3D source will be detected automatically, and options will not be selectable.

Top and Bottom Displays in Top and Bottom format. Frame Sequential Displays in Frame Sequential format.
	3D Sync Invert Enables or disables the 3D Sync Invert function.
Aspect Ratio	Select the aspect ratio of the projected image. Aspect Ratio Description 4:3 Scales an image so that it is displayed in the center of the screen with a 4:3 aspect ratio. This is most suitable for 4:3 images like computer monitors, standard definition TV, and 4:3 aspect DVD movies, as it displays them without aspect alteration. 16:9 Scales an image so that it is displayed in the center of the screen with a 16:9 aspect ratio. This is most suitable for images which are already in a 16:9 aspect, like high definition TV. L.BOX For non-16:9 letterbox source and if you use an external 16:9 lens to display 2.35:1 aspect ratio in full resolution. Full Extends the image to fully fill the screen. Auto Scales an image proportionally to fit the projector’s native resolution in its horizontal width. This is suitable for the incoming image which is neither 4:3 nor 16:9 and you want to make the most use of the screen without altering the image’s aspect ratio.
Zoom	Reduces or magnifies the projected image.
Keystone	Option Description Four Corners Adjusts each corner to make a square image when the projection surface is not level. NOTE: While adjusting the Four Corners, the Aspect Ratio, and Zoom menus will be disabled. To enable them, reset the Keystone settings to default. H. Keystone Adjusts image distortion horizontally.

Compliance Information

This section addresses all connected requirements and statements regarding regulations. Confirmed corresponding applications shall refer to nameplate labels and relevant markings on the unit.

FCC Compliant Statement

This device complies with part 15 of FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy, and if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

Warning: You are cautioned that changes or modifications not expressly approved by the party responsible for compliance could void your authority to operate the equipment.

Industry Canada Statement
